The all-natural Hestra Leather Balm is formulated to protect your sport gloves and is a great way to prevent leather from drying out. Prolongs the life, suppleness and water repellant properties of the leather. Apply as needed with a polishing cloth, rub in until the leather is saturated. Note that light leathers may darken somewhat. Hestra Leather Balm is a leather conditioner, it is not a dedicated leather waterproofing agent. We recommend only using the leather balm for sport gloves in goat leather or cowhide leather.
